Lightning Rod Questions

[CO Hugh]

I recall reading a Denver post article, a long time ago about a guy in boulder who designed a system to dissipate the lightening so it would not strike. It looked like a bunch of wires in a sphere, so like a porcupine.

This is the only type I've come across, in Boulder actually. Those balls were accompanied by V shaped spikes about 8" tall every 12" along the parapet walls. I thought it was to keep birds from perching, but the spikes were tied into the lightning balls. It sure made it frustrating to climb around to different sections of roof; must have stabbed myself 50 times. No birds though.

I have worked on several homes that use this system.. Not pretty to look at but supposedly works better than the old rod system.
